WHEN IS THE WEATHER WET IN HAWAII?
Some recent weather history on the Hawaiian Islands: the summer of 2015 was a very active one. It marked one of the strongest El Niño patterns in recorded history, which meant that warmer water temperatures along the equator brought higher numbers of tropical storms and hurricanes across the Pacific Ocean. El Niño was blamed for other strange weather patterns on the mainland that winter. There was flooding in some parts of the world, and severe drought conditions in others well into the spring of 2016. Here in Hawaii, the storm activity that crept across the Central Pacific made for noticeably wet weather. In 2016, that spring and summer never dried up; the moderate to heavy rains continued for the rest of the year, with some areas of the island receiving twice as much rain as usual. In early 2017, the weather began to settle into a more normal pattern; however, the weather in the rainforest is very unpredictable. If you are wondering what the weather is going to be like during your scheduled tour date, you may have to wait until 48 hours before your tour, unless a larger front, system or tropical storm is forecast. Also keep in mind, weather can vary wildly from shore to shore. It’s common for the weather in Kaanapali to be dramatically different from the weather in Haiku. We can tell you how much rain has fallen or is expected at the activity site within the next few days.
WHAT DO WE DO WHEN IT RAINS?
When heavy rain falls over the northern part of the island, it impacts Rappel Maui tours in a few ways. We operate rain or shine, and we tell all of our guests to expect at least a little rain, even if it’s a few minutes of mist. There is frequently rain in the rainforest, and it’s evident from how lush and green the surroundings are at the activity location that is just a few miles from one of the wettest parts of the island: Hana. If heavy rains or prolonged periods of steady rains cause the streams to swell to levels that are unsafe for swimming, we operate the classic tour on a normal schedule and use alternative rappel stations that are a safe distance from the water course. Sometimes those stations are right next to the waterfall flow, ending in the ponds, and other times, when the falls are roaring and raging, we use jungle walls and cliffs that are farther away from the stream flow. The times when we do not operate due to weather is when extreme conditions cause road closures, landslides or widespread outages.
The main role of your guides is to make sure that everyone has a safe and enjoyable day. Safety is their first priority, and a generous portion of their attention is spent on looking out for one of the least forgiving dangers of rappelling: flash flooding. There are times when the water in the streams is not high or swift, and there’s blue sky above. Danger is not obvious to the average guest, but the guides opt to use rappel stations not directly in the water course. What gives? The local papers are full of accounts of visitors and locals alike getting stranded–or much worse–after seemingly safe conditions turned ugly within the period of a few seconds. When guests ask guides what made them veer from the preference of using the waterfalls, there’s usually a good reason based on ground saturation, the weather upstream, and river gauge readings taken before the tour began. Guides don’t take chances with your safety or theirs; if invisible dangers change your tour, and you’re unsatisfied or concerned, please call the reservations line to talk about your personal experience. And if you’re ever interested in seeing for yourself what can happen when untrained explorers are caught off guard, this video and accompanying story is an excellent cautionary tale.
